Description

Technical Field

[0001] This invention relates to the field of flow control components, and more specifically to flow control components and heating systems. Background Technology

[0002] In heating systems, radiator control valves are core components for regulating indoor temperature and ensuring heating efficiency. The actuator connects to the control valve, acting as a drive unit to operate it. The coordinated operation of the control valve and actuator achieves precise control of the heating medium flow. To ensure control accuracy, the actuator and control valve need to maintain a relative position. However, during long-term operation of the heating system, the pressure and vibration of the heating medium may cause malfunctions in the actuator or control valve. In such cases, the actuator and control valve need to be quickly disassembled for repair or replacement to ensure the continuity of the heating system.

[0003] In related technologies, actuators and control valves are usually positioned using bolts. During installation and disassembly, the bolt holes must be aligned one by one, and the bolts must be tightened or loosened one by one. The operation steps are cumbersome and cannot achieve quick disassembly. Furthermore, the disassembly of bolts must rely on special tools such as wrenches and screwdrivers. If the tools are missing or not compatible during on-site operations, it will directly hinder the disassembly process and reduce maintenance efficiency. In particular, in emergency maintenance scenarios during the heating season, it will significantly extend the downtime. Summary of the Invention

[0004] This invention provides a flow control component and a heating system to solve the problems in the prior art where actuators and control valves are fixed with bolts, the disassembly process is cumbersome, on-site operations rely on professional tools, and the disassembly efficiency is low.

[0009] In one optional embodiment, the locking part includes a first locking plate and a second locking plate, wherein in the locked state, the first locking plate and the second locking plate abut against opposite sides of the inner circumferential surface of the annular plate.

[0010] Beneficial effects: The locking part can apply tension to the annular plate from the radial opposite sides of the annular plate, which helps to improve the connection strength between the locking part and the annular plate, thereby improving the ability of the flow control component to resist vibration and shock during operation and ensuring the operating efficiency of the heating system.

[0011] In one optional embodiment, the transmission unit includes: a screw having a first threaded portion and a second threaded portion, the first threaded portion and the second threaded portion being arranged axially along the screw and having opposite thread directions; the screw being connected to the driving unit; a first slider being threadedly connected to the first threaded portion; a first locking plate being connected to the first slider; and a second slider being threadedly connected to the second threaded portion; the second locking plate being connected to the second slider; the driving unit driving the screw to rotate, causing the first slider and the second slider to move closer together or separate.

[0012] Beneficial effects: By utilizing the screw, the first slider, and the second slider in coordination, the first and second sliders can move synchronously in opposite directions, thereby enabling the first locking plate and the second locking plate to move synchronously in opposite directions. Simply rotating the screw is sufficient to achieve the engagement and disengagement of the locking part and the annular plate, making operation labor-saving and convenient, requiring no special tools. It allows for quick fixing and disassembly of the control valve and actuator, shortening installation and disassembly time, and is suitable for emergency maintenance scenarios. Furthermore, the threaded drive has a self-locking characteristic, ensuring a stable fixing state of the locking part and preventing loosening due to vibration during operation, thus guaranteeing connection reliability.

[0013] In one optional embodiment, the control valve further includes a fixing member that passes through the side wall of the mounting groove. The fixing member is provided with a sliding groove, and both the first slider and the second slider can be slidably inserted into the first sliding groove.

[0014] Beneficial effects: The locking mechanism can be installed on the control valve. By using the first and second sliders to cooperate with the first slide groove, the movement smoothness of the locking part can be improved, deviation can be avoided, the reliability of the cooperation between the locking part and the annular plate can be improved, the vibration and impact during operation can be resisted, and the operating efficiency of the heating system can be guaranteed.

[0015] In one optional embodiment, the bottom wall of the mounting groove is provided with a second sliding groove, and the locking part has a guide block, which is slidably inserted into the second sliding groove.

[0016] Beneficial effects: It can provide precise guidance for the movement of the first and second locking plates, counteract the lateral forces generated when the first and second locking plates move, ensure the smooth movement of the first and second locking plates, ensure the accuracy of the engagement of the positioning groove and the positioning block, improve the operational stability of the locking mechanism, and make the installation and disassembly process smoother and more efficient, adapting to the needs of frequent maintenance.

[0017] In one alternative embodiment, the outer peripheral surface of the locking portion is configured as an arcuate structure that adapts to the inner peripheral surface of the annular plate.

[0018] Beneficial effects: The fit between the locking part and the annular plate is tighter, reducing the probability of relative wobbling between the locking part and the annular plate, which helps to reduce noise and improve the accuracy of the engagement between the positioning groove and the positioning block.

[0019] In one alternative embodiment, the actuator further includes an annular protrusion disposed on the outer peripheral surface of the annular plate; the flow control assembly further includes a sealing ring abutting between the annular protrusion and the end face of the mounting base.

[0020] Beneficial effects: After the actuator and control valve are installed and positioned, the sealing ring is compressed between the annular protrusion and the mounting seat. The sealing ring can seal the gap between the annular protrusion and the mounting seat, effectively enhancing the sealing performance at the connection between the actuator and the control valve, preventing leakage of heating medium, and ensuring the sealing and safety of the heating system.

[0021] In one optional embodiment, the flow control component includes a limiting block with a limiting groove and a notch on the inner circumferential surface of the limiting groove; the actuator further includes a drive shaft, the annular plate is arranged around the drive shaft, the control valve includes a rotating shaft disposed in the mounting groove, one of the drive shaft and the rotating shaft is connected to the limiting block, and the outer circumferential surface of the other is provided with a limiting protrusion, the limiting protrusion being inserted into the notch.

[0022] Beneficial effects: The snap-fit ​​connection between the limiting protrusions and notches enables quick connection between the rotating shaft and the drive shaft without the need for bolt tightening, making operation convenient. Multiple limiting protrusions and notches can be used, with multiple protrusions spaced circumferentially along the limiting groove. The corresponding engagement of multiple protrusions and notches improves the uniformity of transmission between the rotating shaft and the drive shaft, resulting in smoother power transmission, preventing component damage due to uneven force during operation, and ensuring the adjustment accuracy of the flow control components.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] The terms "first," "second," etc., are used for descriptive purposes only and have no sequential or technical meaning, nor should they be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Directional terms used in this application, such as "upper," "lower," "inner," and "outer," are merely for reference to the orientation shown in the accompanying drawings. The use of directional terms is for better and clearer explanation and understanding of this application, and not to indicate the orientation of the referred device or component in an actual application scenario.

[0037] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0038] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0039] According to an embodiment of the present invention, in one aspect, a flow control component 1 is provided, the flow control component 1 including a control valve 100, an actuator 200 and a locking mechanism 300.

[0040] The control valve 100 includes a mounting base 110 with a mounting groove 111. The actuator 200 includes an annular plate 210 inserted into the mounting groove 111. The locking mechanism 300 includes a drive part 310, a transmission part 320, and a locking part 330. The drive part 310 is located outside the mounting groove 111. The transmission part 320 is connected between the drive part 310 and the locking part 330. The locking part 330 is located inside the mounting groove 111. The drive part 310 drives the locking part 330 to switch between a locked state and an unlocked state through the transmission part 320. In the locked state, the locking part 330 abuts against the inner circumferential surface of the annular plate 210. In the unlocked state, the locking part 330 is separated from the annular plate 210.

[0041] For example, the outer peripheral surface of the annular plate 210 and the inner peripheral surface of the mounting groove 111 are fitted together. In the locked state, the annular plate 210 is held radially between the locking part 330 and the mounting base 110, thereby improving the connection stability.

[0042] The mounting base 110 of the control valve 100 can be connected to the pipe 2 of the heating system. The actuator 200 can be used to adjust the opening of the control valve 100 to control the flow rate of the heating medium in the pipe 2 and more accurately regulate the indoor temperature.

[0043] In this application, after the annular plate 210 is inserted into the mounting groove 111, the driving part 310 drives the locking part 330 to switch to the locked state via the transmission part 320. The locking part 330 abuts against the inner circumferential surface of the annular plate 210, and the locking part 330 can fix the relative position of the annular plate 210 and the mounting groove 111, so as to fix the relative position of the control valve 100 and the actuator 200. When it is necessary to disassemble the control valve 100 and the actuator 200, the driving part 310 drives the locking part 330 to switch to the unlocked state via the transmission part 320. The locking part 330 separates from the inner circumferential surface of the annular plate 210, and the control valve 100 and the actuator 200 can be positioned relative to each other. At this time, the annular plate 210 can be pulled out from the mounting groove 111.

[0044] In this way, the locking mechanism 300 enables the control valve 100 and the actuator 200 to be quickly locked and unlocked without the need for bolt tightening or special tools. The connection is strong and can withstand vibrations during the operation of the heating system, preventing the actuator 200 from shifting relative to the control valve 100. Furthermore, disassembly is simple and efficient, significantly reducing maintenance downtime, further optimizing the installation and disassembly experience, improving the practicality of the device, adapting to emergency maintenance scenarios, balancing connection stability and ease of operation, and ensuring the operating efficiency of the heating system.

[0045] In some embodiments, such as Figure 4 As shown, the locking part 330 includes a first locking plate 331 and a second locking plate 332. In the locked state, the first locking plate 331 and the second locking plate 332 abut against opposite sides of the inner circumferential surface of the annular plate 210. In this way, the locking part 330 can apply tension force to the annular plate 210 from opposite radial sides, which helps to improve the connection strength between the locking part 330 and the annular plate 210, thereby improving the ability of the flow control assembly 1 to resist vibration and shock during operation and ensuring the operating efficiency of the heating system.

[0046] Specifically, such as Figure 4 As shown, the transmission unit 320 includes a screw 321, a first slider 322, and a second slider 323.

[0047] The screw 321 has a first threaded portion 324 and a second threaded portion 325, which are arranged axially along the screw 321. The threads of the first threaded portion 324 and the second threaded portion 325 are in opposite directions. The screw 321 is connected to the drive unit 310. The first slider 322 is threadedly connected to the first threaded portion 324, the first locking plate 331 is connected to the first slider 322, the second slider 323 is threadedly connected to the second threaded portion 325, and the second locking plate 332 is connected to the second slider 323. The drive unit 310 drives the screw 321 to rotate, causing the first slider 322 and the second slider 323 to move closer together or separate.

[0048] For example, the drive unit 310 can be a rotary handle, by which the user can rotate the screw 321. When the drive unit 310 drives the screw 321 to rotate clockwise, the first slider 322 and the second slider 323 move away from each other along the axial direction of the screw 321; when the drive unit 310 drives the screw 321 to rotate counterclockwise, the first slider 322 and the second slider 323 move closer to each other along the axial direction of the screw 321. Alternatively, when the drive unit 310 drives the screw 321 to rotate counterclockwise, the first slider 322 and the second slider 323 move away from each other along the axial direction of the screw 321; when the drive unit 310 drives the screw 321 to rotate clockwise, the first slider 322 and the second slider 323 move closer to each other along the axial direction of the screw 321. This application does not limit this; for ease of description, the following example uses the scenario where the first slider 322 and the second slider 323 move away from each other along the axial direction of the screw 321 when the drive unit 310 drives the screw 321 to rotate clockwise.

[0049] After the annular plate 210 is inserted into the mounting groove 111, the annular plate 210 surrounds the locking part 330. At this time, the drive part 310 drives the screw 321 to rotate clockwise. The first slider 322 and the second slider 323 move away from each other along the axial direction of the screw 321, causing the first locking plate 331 and the second locking plate 332 to move away from each other along the axial direction of the screw 321 until the first locking plate 331 and the second locking plate 332 abut against the opposite sides of the inner circumferential surface of the annular plate 210. At this time, the locking mechanism 300 fixes the relative position of the control valve 100 and the actuator 200. When it is necessary to separate the control valve 100 and the actuator 200, the drive unit 310 drives the screw 321 to rotate counterclockwise. The first slider 322 and the second slider 323 move closer to each other along the axial direction of the screw 321, which in turn drives the first locking plate 331 and the second locking plate 332 to move closer to each other along the axial direction of the screw 321 until both the first locking plate 331 and the second locking plate 332 are separated from the inner circumferential surface of the annular plate 210. At this time, the control valve 100 and the actuator 200 can move relative to each other.

[0050] In this way, by utilizing the screw 321, the first slider 322, and the second slider 323 in cooperation, the first slider 322 and the second slider 323 can move synchronously in opposite directions, thereby enabling the first locking plate 331 and the second locking plate 332 to move synchronously in opposite directions. Only the screw 321 needs to be rotated to complete the contact and separation between the locking part 330 and the annular plate 210. This operation is labor-saving and convenient, requiring no special tools, and can quickly complete the fixing and separation of the control valve 100 and the actuator 200, shortening installation and disassembly time and making it suitable for emergency maintenance scenarios. Furthermore, the threaded drive has a self-locking characteristic, ensuring the stable fixing state of the locking part 330 and preventing loosening of the locking part 330 due to vibration during operation, thus ensuring connection reliability. The transmission part 320 has a simple structure, is wear-resistant, extends its service life, and further improves practicality and economy.

[0051] Furthermore, such as Figure 4 As shown, the control valve 100 also includes a fixing member 120, which passes through the side wall of the mounting groove 111. The fixing member 120 is provided with a first sliding groove 121, and the first slider 322 and the second slider 323 can be slidably inserted into the first sliding groove 121.

[0052] For example, the fastener 120 includes a fixing plate 122 and two fixing arms 123. The two fixing arms 123 are connected to opposite sides of the fixing plate 122. The screw 321 is rotatably connected to the two fixing arms 123. The locking part 330, the first slider 322 and the second slider 323 are all located between the two fixing arms 123. The first slide groove 121 is provided on the fixing plate 122. The two fixing arms 123 pass through the side wall of the mounting groove 111 to fix the relative position between the mounting base 110 and the fastener 120.

[0053] The fastener 120 and the mounting base 110 can be welded together, or a sealing structure such as sealant or gasket can be provided between the fastener 120 and the mounting base 110 to ensure the sealing effect between the fastener 120 and the mounting base 110.

[0054] Additionally, the flow control component 1 may include a mounting bracket 600 for connection to a wall to fix the position of the heating system pipe 2. Both the fastener 120 and the mounting base 110 can be installed on the mounting bracket 600.

[0055] By setting the fixing part 120, the locking mechanism 300 can be installed on the control valve 100. By using the first slider 322 and the second slider 323 to cooperate with the first slide groove 121, the movement stability of the locking part 330 can be improved, deviation can be avoided, the reliability of the cooperation between the locking part 330 and the annular plate 210 can be improved, the vibration and impact during operation can be resisted, and the operating efficiency of the heating system can be guaranteed.

[0056] In some embodiments, such as Figure 1 and Figure 2 As shown, the actuator 200 also includes an annular protrusion 220, which is disposed on the outer peripheral surface of the annular plate 210. The flow control assembly 1 also includes a sealing ring 400, which abuts against the end face of the annular protrusion 220 and the mounting base 110.

[0057] The sealing ring 400 can be made of elastic, high-temperature resistant materials such as silicone or rubber.

[0058] After the actuator 200 and control valve 100 are installed and positioned, the sealing ring 400 is compressed between the annular protrusion 220 and the mounting seat 110. The sealing ring 400 can seal the gap between the mounting seat 110 and the annular protrusion 220, effectively enhancing the sealing performance at the connection between the actuator 200 and the control valve 100, preventing leakage of heating medium, and ensuring the sealing and safety of the heating system.

[0059] In some embodiments, such as Figure 5 As shown, the flow control assembly 1 includes a limiting block 500, which has a limiting groove 510 and a notch 520 on its inner circumferential surface. The actuator 200 also includes a drive shaft 240, an annular plate 210 surrounding the drive shaft 240, and a control valve 100 including a rotating shaft 140 located in a mounting groove 111. One of the drive shaft 240 and the rotating shaft 140 is connected to the limiting block 500, and the other has a limiting protrusion 241 on its outer circumferential surface, which is inserted into the notch 520.

[0060] For example, the limiting block 500 and the rotating shaft 140 can be integrally formed to improve the connection strength between the limiting block 500 and the rotating shaft 140, and the limiting protrusion 241 can be provided on the outer peripheral surface of the drive shaft 240.

[0061] The snap-fitting engagement of the limiting protrusion 241 and the notch 520 enables a quick connection between the rotating shaft 140 and the drive shaft 240 without the need for bolt tightening, making operation convenient. Multiple limiting protrusions 241 and notches 520 can be used, with multiple limiting protrusions 241 spaced circumferentially along the limiting groove 510. The corresponding engagement of multiple limiting protrusions 241 and multiple notches 520 improves the uniformity of transmission between the rotating shaft 140 and the drive shaft 240, resulting in smoother power transmission, preventing component damage due to uneven force during operation, and ensuring the adjustment accuracy of the flow control component 1.

[0062] In some embodiments, such as Figure 3 and Figure 4As shown, one of the locking part 330 and the annular plate 210 is provided with a positioning groove 211, and the other is provided with a positioning block 334. In the locked state, the positioning block 334 is inserted into the positioning groove 211, and in the unlocked state, the positioning block 334 is moved out of the positioning groove 211. The positioning block 334 can be provided in the locking part 330, and the positioning groove 211 can be provided in the annular plate 210.

[0063] By utilizing the positioning groove 211 and the positioning block 334, the positioning reliability between the locking part 330 and the annular plate 210 can be improved, the relative displacement between the locking part 330 and the annular plate 210 can be avoided, the vibration and impact during operation can be effectively resisted, and the operating efficiency of the heating system can be improved.

[0064] In some embodiments, such as Figure 3 and Figure 4 As shown, the bottom wall of the mounting groove 111 is provided with a second sliding groove 112, and the locking part 330 has a guide block 333, which is slidably inserted into the second sliding groove 112. Both the first locking plate 331 and the second locking plate 332 are provided with guide blocks 333, and the bottom wall of the mounting groove 111 is provided with two second sliding grooves 112, which are spaced apart.

[0065] The sliding engagement between the guide block 333 and the second slide groove 112 provides precise guidance for the movement of the first locking plate 331 and the second locking plate 332, counteracting the lateral force generated when the first locking plate 331 and the second locking plate 332 move. While ensuring the smooth movement of the first locking plate 331 and the second locking plate 332, it also ensures the accuracy of the engagement between the positioning groove 211 and the positioning block 334, improving the operational stability of the locking mechanism 300, making the installation and disassembly process smoother and more efficient, and adapting to the needs of frequent maintenance.

[0066] In some embodiments, such as Figure 2 and Figure 4 As shown, the outer peripheral surface of the locking part 330 is constructed as an arc-shaped structure that adapts to the inner peripheral surface of the annular plate 210. In this way, the fit between the locking part 330 and the annular plate 210 is tighter, reducing the probability of relative wobbling between the locking part 330 and the annular plate 210, which helps to reduce noise and improve the accuracy of engagement between the positioning groove 211 and the positioning block 334.

[0067] In some embodiments, such as Figures 1-3 As shown, the actuator 200 also includes a first positioning post 230, and the control valve 100 includes a second positioning post 130. The second positioning post 130 is disposed on the outer peripheral surface of the mounting base 110, and the first positioning post 230 and the second positioning post 130 are inserted into each other.

[0068] For example, the actuator 200 also includes a first positioning seat 250, a first positioning pin 230 inserted into the first positioning seat 250, and the control valve 100 includes a second positioning seat 150, which is disposed on the outer peripheral surface of the mounting seat 110. The second positioning pin 130 is inserted into the first positioning seat 250. The second positioning pin 130 can be inserted into the first positioning pin 230, or the first positioning pin 230 can be inserted into the second positioning pin 130.

[0069] By using the first positioning pin 230 and the second positioning pin 130 to plug and match, the actuator 200 and the control valve 100 can be quickly and initially positioned without manual calibration. This ensures the precise docking of the drive shaft 240 and the rotating shaft 140, as well as the precise alignment of the positioning block 334 and the positioning groove 211, avoiding repeated adjustments during installation and further simplifying the installation and disassembly process.

[0070] According to an embodiment of the present invention, in another aspect, a heating system is also provided, the heating system including the above-described flow control component 1.

[0071] The heating system of this invention, utilizing the flow control component 1 described above, requires no professional tools, and has simple installation and disassembly steps with high operating efficiency.
